7. Click the Add Bricks button to select bricks to add to the volume. Bricks must be created externally on the Gluster Storage nodes.
What does it mean with "created externally"? The next step from os point would be volume creation but it is indeed what I would like to do from the gui...

It seems I have to de-select the checkbox "Show available bricks from host" and so I can manually the the directory of the bricks I see that bricks are mounted in /gluster/brick3 and that is the reason it does not show anything in "Brick Directory" drop down filed. If bricks are mounted under /gluster_bricks then it would have detected automatically. There is an RFE which is raised to detect bricks which are created manually.
BTW: I see that after creating a volume optimized for oVirt in web admin gui of 4.1.2 I get slight option for it in respect for a pre-existing volume created in 4.0.5 during initial setup with gdeploy.
NOTE: during 4.0.5 setup I had gluster 3.7 installed, while now I have gluster 3.10 (manually updated from CentOS storage SIG)
Making a "gluster volume info" and then a diff of the output for the 2 volumes I have:
